gpu teaching kit: libwb documentation

Is there any documentation for libwb that I can point my students at?

The lab description Module[2]-DeviceQuery.pdf mentions, at the bottom of page 2, a tutorial page that describes the functionality of the wb+ methods, but I have not been able to find it.

Thanks

I believe what you are after can be found here: Tutorial. We will update this in the Teaching Kit, thanks for pointing out.
